Microscopic Studies of the Interacting Boson Model


Edited by T. Mizusaki and T. Otsuka

The Interacting Boson Model is a unique framework which can be used for describing a variety of low-lying states of various nuclei in an unified way. Since its birth, it has contributed significantly to the study of the nuclear structure. These contributions stem from its simplicity and its group theoretical character, while the primary contributions are in phenomenological description of collective states. However, the nucleus is a finite quantum system where nucleons interact strongly. Thus, the interrelationship between the Interacting Boson Model and the nucleon degrees of freedom in nuclei, usually referred to as the microscopic study of the Interacting Boson Model, is one of the important issues for the success of this model This supplement is organized over various works on this issue. As for the nature of this series of supplements, relevant articles written by physicists in Japan are collected: a pre-historical document, a review of the boson mappings, tests of the various boson Mappings and their applications to the real nuclei.
